This is not an immigration issue.  I would:
1.  Get an attorney to send her a "Cease and Desist" letter.
2.  Ignore her threat.

Thanks everybody! Looks like we can move forward with some of these programs then. I'll check back here to let you guys know how they go and if its something that could be beneficial to others here in the future.

you can have legal marriage anywhere u want, but even got married in US wont gave ur husband immediate status. 
in the future if he wants to come to the US, u have to apply for spouse visa while he is waiting outside USA

You don't need to prove bonafide marriage under the 5 year rule and there is no effect. Why would it? It says very plainly in the N400 that for the 5 year rule, the main eligibility requirement is that you've been a PR for 5 years. No mention of marriage under that rule.

Like the title said, I filed an i485 instead of an i751..  not even sure how I made such a mistake 🤦🏼‍♀️
We already did his biometrics and the case is being processed since May.
My hubbys temp green card expired last November, CR1.
 
What are my remedy options? 

You won't get a refund for filing the wrong form. File the proper form - they may just use the biometrics he did for I-485 for his I-751. 

1. if u married ( no 2) u cant apply for fiance visa. fiance only if u havent get married
2. u cant apply visa in a country if you are not resident / legal residences in that country
3. u can do utah online wedding, visit her in her country to consumate the marriage and APPLY spouse visa ( roughly 18 months- 2 years)
 
immigration journey is expensive and take patience. nothing is fast / express
 

And have certified copy of marriage certificate in hand. 😉  You can have everything ready ahead of time and just add the certificate and file.

The only timing detail that matters about filing I-130 is that it must be done after you guys marry.

You can submit it any time after marriage.

Just on the fact that it's important for him to travel means you should definitely go for CR1. K1 plus adjustment is cumbersome, annoying and he will most certainly go insane not being allowed to leave the US. K1 and adjustment of status are also separate processes, meaning separate fees for both, meaning a higher grand total when you add it all up. CR1 is a much more efficient process on the basis that it automatically makes the immigrant a green card holder/permanent resident upon entry with the visa.

Unfortunately, this is just how the process is with the US immigration system. As Boiler said, even if an expedite were granted, it still isn't lightning fast. Governments and bureaucrats take however long they take and the hard truth is that applicants are at the mercy of however long it takes. A lawyer has no power or influence in speeding up a case.

You can report this to USCIS.  A crime of CIMT committed within 5 years after admission is deportable.  You know his case number, write a letter to USCIS with a copy of the letter from CPS, and mail it to them - Express Mail

His visa process was over when he originally entered with the CR-1 visa 2 years ago. You're only talking about his permanent residency process now. He's ok to travel and to return any time before his green card expires.

I agree, CR1.  Also, as @Crazy Catshowed, the CR1 is cheaper.

Every couple has their own priorities, and each couple must decide which visa is better for their situation.
K-1        
    More expensive than CR-1    
    Requires Adjustment of Status after marriage (expensive and requires a lot of paperwork)    
    Spouse can not leave the US until she/he receives approved Advance Parole (approx 6-8 months)    
    Spouse can not work until she/he receives EAD (approx 6-8 months)    
    Some people have had problems with driver licenses, Social Security cards, leases, bank account during this period    
    Spouse will not receive Green Card for many months after Adjustment of Status is filed.
    A K-1 might be a better choice when 18-21 year old children are immigrating also
    In some situations, marriage can affect certain Home country benefits, making a K-1 a better choice   
    A denied K-1 is sent back to USCIS to expire
    
CR-1
    Less expensive than K-1    
    No Adjustment of Status(I-485, I-131, I-765) required.    
    Spouse can immediately travel outside the US    
    Spouse is authorized to work immediately upon arrival.    
    Spouse receives Social Security Card and Green Card within 2 or 3 weeks after entering the US    
    Opening a bank account, getting a driver's license, etc. are very easily accomplished with GC, SS card, and passport.
    Spouse has legal permanent Resident status IMMEDIATELY upon entry to US.
   

 

OP's wife is Canadian. She doesn't need to apply for B1/B2 just to visit. She'd only need one if CBP eventually tells her to get one, which would probably happen due to visiting too much.
 
Adjustment of status is not a viable option for you.

Having a job offer in the US actually shows immigrant intent, so why would they believe that she doesn't have immigrant intent?
If she wants to apply for a tourist visa, just having a lease in her home country is not enough. Especially with her job situation. 
Yeah, you'll need those for a B1 B2 visa, but they don't prove strong ties.
Not a strong tie either.
Probably good for a B1 B2.
 
Paging @Crazy Cat for his (extremely) useful comparison of K1 vs CR1
 
You've been given toons of answers. You still insist on getting it your own way. At this point, since no answer here is convincing enough, I would strongly advise you to hire an attorney. 
K3s are dead and a waste of money. The choice is between K1 and CR1

If being separated for more than 2-6 months at a time is too much for you. Don't take the job offer. Sounds like you have a great life in Canada so don't mess with moving to the States. 
 
 

I-130 is the easiest and fastest way for her to move permanently to the US without issues. Rescinding your American citizenship is an absurd idea. There's absolutely no reason to do that. Besides, even if you were to pursue that, that process PLUS trying to get an H1B or TN would take time. At the end of the day, it'd probably take around the same amount of time as just waiting for the spousal visa. You also would not be able to start your job right away. You'd have to wait for H1B visa to be processed and that can take a while.
 
And there is no reason to pursue a non-immigrant visa. Not all non-immigrant visas allow for a green card, which is ultimately what your wife needs to live and work permanently in the US. Non-immigrant visas come with all sorts of conditions and restrictions that your wife would have to adhere to. She would also have to qualify on her own terms and merits for a non-immigrant visa, depending on which one you look at.
 
Stick to the I-130. Sorry but if you're unable to handle some separation time, then consider just staying in Canada. Separation time is part of the deal if you're in a relationship where you don't have the same citizenship and must deal with these government legal processes.
